Well you know, many people changed their mind in France and Sarkozy gained many votes because of the growing feeling of insecurity (he was minister of interior you know). He was elected for various reasons. He did not make many mistakes, he proved himself an able minister on both Interior and Finances. His opponent, Segolene Royal had no charism and no program. Many people in France are waiting for a wind of change... Well that's a big debate which probably has no place on a NG forum ;-)
Where are you from by the way, you are very well informed about our French President (actually, even better than I am).
